A special training team has been dispatched to a federal building in Detroit to remind security staff that the proper protocol to follow after finding a suspicious package does not involve leaving it in lost and found for three weeks. The bomb squad was called in after staff at the McNamara Federal Building finally X-rayed the package and discovered it contained a pipe bomb, ABC News reports.

A union official says the private security guard—who has now been suspended—put the package in storage after discovering it outside the building, which houses the FBI, IRS, and offices for Sen. Carl Levin. The device was detonated and the remains sent to FBI headquarters for testing. "Our priority is determining exactly what it was and who left it," an FBI agent tells the Detroit News.
